Polar bears have started to mutate due to climate change: will this save the species.

According to ТСН: Forecasts for polar bears in the Arctic are grim: scientists claim that more than two-thirds of this species could disappear by 2050, and by the end of the century, their existence may come to an end. The main reason for this process is the melting of sea ice, which serves as a platform for their hunting of seals. However, new research brings some hope: bears have begun to adapt to new conditions.

Jumping Genes

Researchers from the University of East Anglia studied the blood of bears from two regions of Greenland: the cold northeastern and the warmer southeastern.

It turned out that bears from the southern region have more active 'jumping genes' (transposons) — these are sections of DNA that can move around the genome, turning certain functions of the organism on or off.

'They copy themselves and jump freely, and they do this more often when the animal is under stress — in this case, when it is very hot or starving,' explained study author Dr. Alice Godden.

Switching to a 'Diet'

These genetic changes affect the animals' metabolism. Scientists noticed changes in genes related to fat processing.

This suggests that bears in the southeast are gradually adapting to changes in diet. Previously, they preferred fatty seals, but now, weakened by the reduction of ice and difficult hunting, they have started to switch to plant-based food or look for new food sources on land.

Will this save the species?

Dr. Godden considers this discovery a 'ray of hope'. Nature impresses with its ability to survive.

'Provided these polar bears can find enough food and mates for reproduction, this suggests that they could potentially survive this new challenging climate,' says the scientist.

However, genetic adaptation is not a definitive solution to the problem. The Arctic is warming two to three times faster than other regions of the planet. Scientists emphasize that mutations may give bears a little more time, but without reducing carbon emissions and stopping global warming, their fate remains at risk.

Such scientific studies can provide a new perspective on the adaptation of wild animals to changing living conditions. They demonstrate how nature is attempting to find ways to survive, but global ecological issues require urgent solutions to protect these species from the threat of extinction.
